A human being whose mental and physical abilities have been enhanced through genetic engineering. Coordinators learn more quickly than normal humans, and their bodies are stronger, faster, and virtually immune to disease. Due to these differences, they have often been viewed with jealousy and mistrust by unmodified Naturals. In recent decades, a worldwide ban on genetic modification and a rising tide of anti-Coordinator sentiment have driven most of Earth's Coordinators to relocate to the orbital settlements known as PLANTs.
The genetic modifications that create a Coordinator can be performed only in the earliest stages of embryonic development. However, these genetic enhancements are then passed on to the Coordinator's children. When normal parents have their children turned into Coordinators, the children are described as first-generation Coordinators, whose own children will then be second-generation Coordinators, and so forth.
The era of the Coordinators began in the year C.E. 15, when George Glenn revealed the secret of his origins and released the necessary genetic engineering techniques onto the worldwide network. However, such genetic modification remained illegal for many years, and so the earliest Coordinators were born and raised in secret. The Coordinator boom started in earnest in C.E. 30, and came to an end with the adoption of the Torino Protocol in C.E. 55, when genetic modification was once again prohibited everywhere on Earth.
